Bill,

"-ldevices.rts-merge -lc-merge" was something I was playing with the
older versions of the compilers to get -O4/-O5 working. It might not
be appropriate for the current version of compilers/libraries. [and
the problems with -O4/-O5 don't exist anymore - so there is no more
need for the merge]

For my usage, its:

diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpicc /home/balay/bin/mpicc.ibm
diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpicxx /home/balay/bin/mpicxx.ibm
diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpif77 /home/balay/bin/mpif77.ibm

And

diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpicc /home/balay/bin/mpicc.gnu
diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpicxx /home/balay/bin/mpicxx.gnu
diff /bgl/BlueLight/ppcfloor/bglsys/bin/mpif77 /home/balay/bin/mpif77.gnu
